The compatibility audit does not cover the single-node/single-drive (FS mode)
case explicitly. This documents a production upgrade from the final community
release (RELEASE.2025-10-15T17-29-55Z) to Silo RELEASE.2026-09-16T00-00-00Z:
why standalone deployments are low-risk (schema retention, no multi-node REST
concern, IAM tightening not applicable), the validated procedure with layered
verification, field results (~5.9k objects, zero migration, zero hardening
rejections, full app regression passed), and the post-upgrade behavior changes
to review per client (TLS defaults, If-Match on DeleteObject, multipart listing
cap, TRUSTED_PROXIES default).
